Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-6 is please referred to, the utility model provides a kind of technical solution: a kind of dust cover of New Coal Mine conveyor belt, Including conveyer belt 1, the two end axles of conveyer belt 1 are connected and fixed on inner frame 2, and are welded on the outside wall body of inner frame 2 outer Frame 3, outer framework 3 and convex block 12 are welded to connect, and 3 top end surface of outer framework extends to form groove 4, and groove vertically downward 4 are internally provided with rotating bar 5, transmission gear 6, chain 7 and sliding rail 8, the both ends of rotating bar 5 and the 3 wall body axis of rolling of outer framework Flexible connection is held, and is welded with transmission gear 6 in rotating bar 5, and transmission gear 6 is meshed with the inner ring of chain 7, slides rail 8 bottom end is welded on 3 wall body of outer framework, and the top for sliding rail 8 is embedded in the bottom end wall body of sliding bar 9, sliding bar 9 Rubber rack gear 10 is bonded on wall body, and the bottom end of sliding bar 9 extends in groove 4, and sliding bar 9 and dustcloth 11 sew It is integrated, rubber rack gear 10 is meshed with the outer ring of chain 7, and convex block 12 is connected with outer framework 3, and rolling bearing on convex block 12 It is connected with hand crank 13, and the bottom end of hand crank 13 extends to the inside of convex block 12, the bottom end of hand crank 13 It is sequentially connected between a rotating bar 5 of its horizontal alignment by driving belt 14, and driving belt 14 is worn from sliding rail 8 It crosses.

Inner frame 2, outer framework 3, groove 4 and sliding rail 8 are in " O " shape structure, and between rotating bar 5 inside groove 4 etc. Away from being uniformly distributed, the design of " O " shape structure can make sliding bar 9 that dustcloth 11 be driven to rotate around conveyer belt 1, in turn It can carry out different direction to conveyer belt 1 to block, rotating bar 5 is equidistantly uniformly distributed, and transmission gear 6 thereon can make Chain 7 is in tensioning state, and rubber rack gear 10 can smoothly be driven to rotate.

The section of groove 4 is ringent rectangular configuration in top end surface, and the opening width of 4 top end surface of groove is less than The diameter of sliding bar 9, the structure design of groove 4, moves sliding bar 9 smoothly inside it, will not be hindered, It is structurally reasonable.

Sliding bar 9 is equally distributed on sliding rail 8, and the spacing between 2 sliding bars 9 of outermost and rubber rack gear 10 length are consistent, and are greater than the length of conveyer belt 1, in this way when all sliding bars 9 turn to 1 two sides of conveyer belt, sliding bar 9 On dustcloth 11 conveyer belt 1 can be sheltered from completely, good dustproof effect, while rubber rack gear 10 can be by multiple sliding bars 9 connections are in one, when rubber rack gear 10 is mobile with chain 7, all sliding bars 9 can be driven to move on sliding rail 8, into And drive dustcloth 11 mobile.

The " T " shape structure of section of rail 8 is slided, and sliding between rail 8, sliding bar 9 and chain 7 is stainless steel material, The structure of " T " shape structure designs, and sliding bar 9 is fixed on sliding rail 8, without departing from, while 9 bottom end of sliding bar with The "T"-shaped end of sliding rail 8 is in contact, when and be not fixed, can carry out it is opposite slide, and then sliding bar 9 can be on sliding rail 8 Rotation, and then sliding bar 9 can drive dustcloth 11 to carry out position adjusting, the design of stainless steel material, so that its intensity is big, no Perishable, long service life ensure that its operation is stable.

Working principle: in use, 2 fixed placement of inner frame is good, this is manual rotation manual crank 13, hand crank 13 It is driven by driving belt 14 and is rotated with a rotating bar 5 of its horizontal alignment, the transmission gear 6 in the rotating bar 5 turns therewith It is dynamic, and chain 7 is driven to rotate on remaining transmission gear 6, when chain 7 rotates, the rubber rack gear engaged can be driven 10 is mobile, and it is mobile along sliding rail 8 that rubber rack gear 10 drives sliding bar 9, and then when sliding bar 9 moves in groove 4, can band Dynamic dustcloth 11 thereon is rotated around conveyer belt 1, at this moment according to wind direction by the rotation of dustcloth 11 to suitable position, in this way Dustcloth 11 can shelter from wind, and the coal dust on conveyer belt 1 is avoided to be dispelled into air, and last conveyer belt 1 is defeated by coal mine It send to specified processing equipment, coal mine can be fallen down between conveyer belt 1 and inner frame 2.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
